PROCESS OF THE MANUFACTURE OF A msrnmc'rnnm No. 929,383. Specificationof Application filed March 10,

To all whom-it may concern:

Be it known thatl, ALEXANDER BRICK, a 1 subject of the King of Hungary,and resident of XX, Petraschgasse 4-6, Vienna, Austria- Hungary, haveinvented a certain new and useful recess of the Manufacture of a Disinfectant Consisting of Formaldehyde and Ethereal Oils.

I do hereby declare the following to be a full clear and exactdescription or the inventhe same.

Experience has shown that the use of formaldehyde in the form of spra isexceedingly important for disinfecting the interiors of. dwellings,restaurants, theaters, etc. The formaldehyde must, however, be employedin such shape that it neither irritates the mucous membrane, nor retainsits penetraton the contrary, it should be so combined with ethereal oilsas to be invigoratin For this purpose it is necessary to enipl 0y theformaldehyde in combination wit ethereal oils and with such' a solvent,-that it forms an emulsion with the ethereal oils with which it isCombined, also with Water, and that it can be sprayed with this. Thisobject is best-obtained, by proceeding as follows:--A mixture is made ofabout 2 kilos. of soap solution gontaining about 40% alcohol (this canbe soda or potash soap), a} kilogram rosemary oil, 2 kg. juniper oil, 5;kilo. oil of juniper berries, 200 grams essence of turpentine, i kilo.geranium oil, .5 kilos. r entinoifl kilos. oil of lemon, rams musk. Tothis mixture, there are ad ed,-;in the reflex cooler, under constantheat and'stirring, gradually, 5 kilos. formaldehyde. The iorinaldehydeLetters Patent. Patented July 27, a.

mixture, or paraformaldehyde can be heated in a retort, and thegasdeveloped therefrom conducted into the liquid in the-reflex eoole'r.In both cases the m'ixtu tion of the formaldeh 'k'le is kept constantlyat a temperature of about 30 C. The para formaldehyde ran, however, alsobe put into the mixture and carried over in the form of gas by heating.In this last case, however the mixture must The heating of the mixtureinthe reflex cooler is continued some time after the addition of theformaldehyde, and thereby coir-1 densation products or" the formaldehydeare obtained with-tho ethereal oils, which, when highly diluted with wtheir components, namely, the-active formaldehyde and into ethereal oil.The essence recovered in the reflex cooler is, after cooling, mixed withthree to four-times the amount of potash or soda soap made,- from sesameor other oils, which soap contains about 30% of free unsaponified oiland is combined with about 5% of alcohol.

Having thus fully set forth and described my invention, What I claimis:"
